    I learnt most of what I know about the TA block from reading Jim's E85 555cui build thread. Most of what you need to know is thankfully written by Jim.

    The guy is a retired mechinest that is 73 years old. About 35 years ago when Big Block Chevy engines were just coming out in aluminum and were priced very high. Since in his opinon they were so high and not as strong as he needed he made his own block from a solid block of aluminum.

    I got a set of very earily Aluminum Bulldog heads that has been adjusted by me.

    I went over to see the new engine and got the bad news. The lifter bar hits on three cylinders (one real bad) that I tested, so I even if it hit on one cylinder a new set would be needed.

    The further I got the the rear the worse/more the lifter hit.

    If it were not for having 820 pounds on the nose (and lifter raised), I would suggest milling the tops of the lifter bores.

    Even that would be a trial and error to get correct.

    Good news was that he got the cam degreed in.

    Talking to my engine builder I was telling him about Royden's lifter valley pan under his intake. After learning of the oil leak/ no vacume he said why don't you build "stands" to hold up the middle of the valley pan to keep the ends down and sealed. Use the holes already drilled and taped in the valley.

    I have the Mopar ( Dodge ) intake conversion that does not have any water flowing through it.

    After some measuring, I fiqured I need them to be 1.272 inches tall. I just cut and countered bored to fit a allen head bolt that is 1.250 long.

    Put the timing cover/water pump on and found the three main bolt holes are not that deep from the face on the right side (close to the oil pump).

    Not sure if the water and oil ports are closer to the front so I desided not to make the holes deeper but to tap to the bottom and trim the bolts.

    Looking at the mounting for the alternater and Procharger, the front of the heads to the block front are different than the iron block.

    Plan "A" and "B" for the alternator mount is going to be changed to something different. The mount I made a few months ago for the alternator and the

    factory mount can not be used so I must make new one.

    My theory is "recovery time". I plan on only running five or so HG to make it easier on the vacume pump.

    The last engine with the Procharger would spew oil after 1/8 mile.

    Rod,

    Was wondering how much you milled off and where on the lifter bore you did the milling.

    In my case it was 2.375" from the base circle of the cam to the top of the lifter bore. It is also 2.375 inches from the roller to the lifter link bar on the older lifter that I was told were TA.

    I was thinking of milling the lifter bores, but the engine was 80% put together when I found it (the bar hitting). I would have to disassemble the entire engine then clean after the milling.

    The 1413-1 lifters came in today and they measure 2.575" from the roller to the lifter link bar.

    I am going to start with these push rods that I had in my iron block to see if they are the correct length.

    It was a few years ago that I did this.. so I don't remember how much I took off. The milling was done straight down from the end rails of block.

    I've considered a larger cam shaft, but Tony at AES has said I won't be able to get a large enough push rod to handle the spring pressure. Have you looked into this? I currently run a Manton 3/8 heavy wall push rod. I have less spring pressure than you. I run TA heads.. so maybe the Bulldog head allows for a bigger push rod.

    In the stock block I Ran 335 on the seat and 850 over the nose with a tall lifter
    (old crane style with seat on top) 200 off set for the Stg4's . I used a 3/8" pushrod
    but it was short 8.050 with the tall lifter no problem. Tried to use the same on the
    Aluminum block but the cross bar on the old style lifter is too low so had to go with new
    style lifter , they are not available in .200 offset because the cup is down inside the lifter and there is no room for
    the pushrod with that much offset. .180 seems to be the max. These lifters made the pushrods longer
    less offset caused interference at the head and i wanted to run more spring pressure with the turbos.
    ended up running tapered pushrods 3/8to5/16 on intakes and 7/16 to 3/8 on the exhaust.
    No problems 350/900 plus.

    Put the lifters in and adjusted the valves (solid lifters). Looks like 3/8 push rods could be used on the Bulldog heads without any cutting.


    Rod how long are your push rods and what is your spring pressures?

    My last set of push rods were 9.925 long with the open pressure being 630 pounds and no issues.

    Mike T. talked to me about making me a set that would be tapered and oil restricted (3/8 on bottom and 5/16 top) if I need a new set.

    Oil pan got here today.

    SRE did a super job. The fit could not be any better.

    oil pan 1.jpg

    Mike T. for some reason drilled and tapped two other bolt holes in the oil pan rail. (I have not asked him why ) All 14 oil pan bolt holes line up.

    Thanks Micheal, I appreciate the compliments!

    I think Mike used the original oil pan bolt pattern on that side, but added the other two holes so the side of the pan could now be straight instead of doglegged. I don't believe Mike knew what was exactly going to develop for the oil pans when the casting / bolt locations were designed many years ago. As it turns out they really aren't needed, but then again they don't affect anything by being there.

    Made a oil pan gasket myself and it was easier that than a stock one will be. Hope it never has to come off as it is gluded on tight.

    Primed it with my 1/2 inch electric drill and it went to 42.5 pounds. After letting it sit over night and no oil drips, I put the upper part of the intake on.

    It is time to drop it into the Skylark and get it hooked up.

    Michael,
    We have those oil pan gaskets in stock. TA1700-455AL. Sorry should have mentioned it. The two extra oil pan bolt holes are used when you modify and use a stock oil pan. This way you only need to modify one side of the pan to get it to fit.

    It is all together just need to cross my fingers and turn the key.

    If it was not for having skunkey fuel, I could have tried to start it tonight. It will be tomorrow before I can get some new fuel.


    Oil pressure. Check



    Look for fuel leaks. Check



    Water installed and checked for leaks. Check


    Elecric fans and elecric water pump. Check



    Did find one small water leak and fixed it (dam worm clamps). Have new T-clamps on the way.



    Oh I do need to install about four quarts of automatic trans flude.
